Preparing the Digital 9000 system for use
Daisy chaining receivers
The EM 9046 receivers feature an integrated antenna splitter so that up to
four receivers can be daisy chained. This allows you to use two antennas/
antenna boosters for up to four receivers. In this case, all receivers have to
use
the same booster frequency range.
왘
Use GZL 9000 antenna cables to connect two antennas via antenna
boosters to the
RF IN N-type sockets
E
and
F
of the first receiver.
왘
Connect the RF OUT N-type sockets of the first receiver to the RF IN N-
type sockets of an additional receiver. To do so, use the RF patch cables
from the EM 9046 CAB cable set.
왘
Repeat the previous steps for up to four receivers.
If you want to pass on word clock signals between daisy chained receivers
and/or if you want to connect daisy chained receivers in a network (see
the following chapters):
왘
Connect the receivers in the same order in which you connected the RF
N-type sockets. Always connect the network sockets from LAN DOWN to
LAN UP and word clock sockets from OUT to IN .
*
If you have installed a MAN card in the first receiver of the daisy chain and if you
use the card‘s word clock as the external master, the connection to the external
word clock generator is no longer required (see next section).
**
This diagram illustrates a convenient way of daisy chaining the receivers.
Sennheiser recommends using an external switch to connect the receivers in a
star topology (see “Connecting receivers in a network” on page 36).
